ARCHAEOLOGICAL IMAGE ENHANCEMENT USING HISTOGRAM
Abstract
Archaeology studies the story of man’s past through his materials remains. The word archaeology comes from the Greek word Archaios – Ancient or Arche – beginning and logos- theory or science .According to one definition, “Archaeology is essentially a method of reconstructing the past from the surviving traces of former societies”. It is a branch of learning that is concerned with the material vestiges of man, “everything made by human beings from simple tools to complex machine from the earliest temples and tombs to palaces. In olden days archaeologists will capture the photos through the camera and they will develop the photos in a photo storage room. In the last twenty five years, a school of archaeologists led by Leuis Binford and David Clark has been strongly championing the cause of archaeology as a scientific discipline. This approach goes under the name “New Archaeology”. Archaeology is undergoing profound transition from interpretation of images displayed on photo to reading images on high-resolution computer screen. As this new era emerges, archaeologists are also starting to see traditional photo delivery replaced by electronic transfer of digital file, and photo storage rooms replaced by archives of computer files. Histogram comes in. It is a simple graph that displays where all of the brightness levels contained in the scene are found, from the darkest to the brightest. These values are arrayed across the bottom of the graph from left (darkest) to right (brightest).
